However, Weiner told TV Guide that Peggy is "part of Don's life", adding: "We knew that [the character] was going to leave - that she had to leave - and that we would see the beginning of a new relationship."

The showrunner added that January Jones continued to appear on Mad Men following her divorce from Don (Jon Hamm).

"Some people do leave the show, and I'm not guaranteeing that [Peggy] will be there or be in that world as much. But when Don divorced Betty, I had all these questions of like, 'I guess [January Jones is] off the show?'

"I was like, 'She's raising his children. You don't think that he's going to have any relationship with her ever again?' ... Peggy is part of Don's life."
